Data were obtained for rubidium in six geological reference materials by isotopic dilution thermal ionisation mass spectrometry (ID‐TIMS) and wavelength dispersive X‐ray fluorescence spectrometry (WD‐XRF). The results found by one technique compare very well with the other within the respective analytical uncertainties and are also in good agreement with data from previously published values. The particular case of low Rb determinations in reference sample BIR‐1 is discussed.
